This is a 092-3125FR-1000 model mirror, a high-quality optical component sourced from EKSMA Optics. It is a curved mirror with a concave base shape and a circular cross-section, featuring a diameter of 25.4 mm and a thickness of 6 mm at the edge. The mirror's effective focal length (EFL) is -500 mm, and its radius of curvature (R1) is -1000 mm, making it a plano-concave spherical mirror.
The mirror is made from UVFS material, specifically UVFS mal- 1965, and is designed to operate within the wavelength range of 600-1100 nm, with a central wavelength of 800 nm. It is coated with an enhanced silver coating, denoted as 'eks enhsil600110045', which provides high reflectivity across the specified wavelength range.
